IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 31,563, dated February 26, 1861.

To all whom 'it may concern:

Be it known that we, GEORGE SEIBEa'r and JOHN SEIBERT, of Ashley, in the county of Washington and State of Illinois, have intion, and Fig. 3 a longitudinal elevation of` the front axle with the wheels thereon.

This invention consistsin an improved method of making a gang-plow, to which a subsoilplow may also be attached whenever it may be desirable.

This gang-plow consists of a peculiarly-constructed frame which is mounted upon three wheels, two of which wheels are placed upon a front axle of peculiar construction. The remaining one, being in the nature of a casterwheel, is attached to the back or rear end ot' the frame.

The following description will enable any one skilled in the arts to which our invention appertains to make and use the same.

Similar letters of reference represent corresponding parts of the drawings annexed.

Upon the drawings, A represents the frame of the gang-plows, which consists of two parallel pieces of wood united upon parallel plains by means ot' adjusting screw rods or studs G Gr, (one of these studs falls under the seat B, so as not to show, in Fig. 1,)by means of which the two beams are adjusted to or from each other when a large or small plow is to be applied. Thus when a ten-inch plow is to be used, so as to make a ten-inch furrow, the beams are to be set ten inches apart, and so in proportion to all other sized plows.

The plows C C are attached to the beams A A by means of the standards F F, which standards are attached to the beams by means of brackets b b b b and latch E and set-screws a. The said brackets are fixed to the top of the frame by means of bolts, directly over a groove cut in the side of each beam to receive the said standard. The set-screws are set in the jaws of the brackets opposite each other, so as to gripe the standard on each side thereof, as shown. The standard is held in the groove cut in the side of the beams by means of the latch E, which is fixed against the side of the beam on a pin or screw, so as to catch in the hook s, which secures it. By this arrangement of mechanical parts the plows can be raised up or shoved down, or taken out and replaced in rive minutes.

The landside ot' this plow has a peculiar shape, as will be seen, the back being curved up like a sleigh-runner, so that the plow can be backed, if desired. The plows, it will be seen, are attached to the standards by means of two bolts, in the manner shown. The front end of the frame-beams on the land side are cut to an angle with their lower surfaces, as shown by d d, in the longitudinal direction. The object of this is to raise the front plow out of the ground when the machineis to be turned, which object is effected by the right-hand end ot' the axle H being made to press against the angular surface as it moves back in the act of turning, the said axle being made to turn around the pin 'n in the front end of one of the framebeams.

The axle H is composed of two parts, J and H, the piece J being xed to the piece H by means ofa pivot-screw, o, about which the said piece plays in a staple. u. Now, the shaft tu which the power is applied to draw themachine is attached to both parts of the said axle, by which means the wheel I is thrown around to the position shown by the red line c c, when the plow is turned to the right, the object of which is to cause the wheel to clear the plow mold-board, and to enable the plowman to turn it short around. The wheels I and D run in the furrows, the wheel D in the furrow made by the plow C and the Wheel I in the preceding furrow, made by the plow C. Now, when it is desired to throw the plows farther in the land the clevis g is adjusted farther to the left in the slot P, this clevis being the connectinglink between thefront axle and the frame.

When it is desired to subsoil, the plow C is taken oft' of the machine, and the subsoib plow is attached to the beam A in the same manner that the other plows are attached to their respective beams. The beam' A is attached to the under side of the main frame, so as to bring the point of support as near the Vplow as possible.

Having thus described the construction and operation of our invention, what We claim as A', when arranged in relation to their respectnew, and desire to secure by Letters Patent, isive parts, substantially in the manner described,
